Modern Warfare 2 the 2nd best-selling game in the US

All-time sales only bettered by Wii Play.

The NPD Group reports that Activision and Infinity Ward's Call of Duty: Modern Warfare 2 has become the second-best selling game of all time in the US.

The blockbuster FPS is now only behind Nintendo's Wii Play in the all-time sales chart, a game which has been selling off the back of its Wii Remote bundle since its launch alongside the Wii back in February 2007.
